Definitions

  • Some of the more common topically applied surfactants are nonionic surfactants, such as polyethoxylated octylphenols and condensation products of propylene oxide with propylene glycol, by way of illustration only. These surfactants are effective in rendering normally hydrophobic polymeric fabrics water wettable. However, the surfactant is readily removed from the fabric, often after only a single exposure to an aqueous liquid. Such surfactants are effective in rendering the hydrophobic polymeric fabric wettable by lowering the surface tension of the aqueous liquid. Such a mechanism must involve at least partial removal of surfactant from the surfaces of the fibers of which the fabric is composed.
  • nonwoven webs Many of the items prepared from nonwoven webs are single use or limited use products. Most of the current nonwoven webs are prepared from polymers which are not considered biodegradable, such as polyolefins. Although currently available disposable baby diapers and other disposable products have been accepted by the public despite the fact that they are not biodegradable, these current products would benefit from improvement in the area of disposal.
  • the biodegradable polymer of the substrate also may contain minor amounts of additives as is customary in the art.
  • the biodegradable polymer may contain pigments, fillers, delustrants, antioxidants, antistatic agents, stabilizers, oxygen scavengers, and the like.
  • the term “hydrophilic biodegradable polymeric coating material” means that the biodegradable polymeric material has a surface free energy such that the polymeric material is wettable by an aqueous medium. That is, an aqueous medium wets the hydrophilic polymeric material with which the substrate is coated.
  • the surface free energy of the hydrophilic polymeric material may be at least about 50 dynes/cm.
  • the surface free energy of the hydrophilic polymeric material may be in a range of from about 50 to about 72 dynes/cm.
  • durable as used herein with reference to a coating of a biodegradable polymeric substrate means that the treated substrate retains its hydrophilic nature even after storage for extended periods of time, for example at least 1 month.
  • durable also means that the treated substrate remains wettable after at least three exposures to an aqueous medium, such as water, saline, and urine and other body fluids.
  • the funnel is located at approximately 7.8 inches (about 200 mm) from the bottom or lower edge of the test assembly.
  • the valve of the funnel is located approximately 10 mm above the top surface of the test assembly.
  • One hundred ml of water having a temperature of 35° C. is placed in the funnel.
  • the valve of the funnel is opened to dispense the water over a period of about 15 seconds.
  • the amount of water which runs off and is collected in the collection means is determined and recorded.
  • a fibrous web is typically considered to pass the modified run-off test if the amount of water collected in the collection means is less than an amount deemed appropriate for a given type of fibrous web.
  • the fibrous web is a lightweight (e.g., having a basis weight of 0.6 ounces per square yard or about 20 grams per square meter) spunbonded nonwoven web, the amount of water collected should be less than 20 ml.
  • the phrase “affinity of the polymeric material for the biodegradable polymer substrate” means that the hydrophilic polymeric material coats the substrate substantially uniformly (i.e., to an extent sufficient to permit the coated substrate to be wet by an aqueous medium), typically after first exposing the substrate to a field of reactive species.
  • partial affinity means that the polymeric material partially coats the substrate. The functional consequence of a partial affinity is that the coated substrate is only partially wettable.
  • nonwoven web means a web having a structure of individual fibers or threads which are interlaid, but not in an identifiable manner as in a knitted web.
  • Nonwoven webs have been formed from many processes, such as, for example, meltblowing processes, spunbonding processes, air-laying processes, coforming processes and bonded carded web processes.
  • the basis weight of nonwoven webs is usually expressed in ounces of material per square yard (osy) or grams per square meter (gsm) and the fiber diameters useful are usually expressed in microns, or in the case of staple fibers, denier. It is noted that to convert from osy to gsm, multiply osy by 33.91.
  • spunbond web refers to a nonwoven web prepared from small diameter fibers of molecularly oriented polymeric material.
  • Spunbond fibers may be formed by extruding molten thermoplastic material as filaments from a plurality of fine, usually circular capillaries of a spinneret with the diameter of the extruded filaments then being rapidly reduced as in, for example, U.S. Pat. No. 4,340,563 to Appel et al., and U.S. Pat. No. 3,692,618 to Dorschner et al., U.S. Pat. No. 3,802,817 to Matsuki et al., U.S. Pat. Nos.
  • Spunbond fibers are generally not tacky when they are deposited onto a collecting surface and are generally continuous. Spunbond fibers are often about 10 microns or greater in diameter. However, fine fiber spunbond webs (having an average fiber diameter less than about 10 microns) may be achieved by various methods including, but not limited to, those described in commonly assigned U.S. Pat. No. 6,200,669 to Marmon et al. and U.S. Pat. No. 5,759,926 to Pike et al., each is hereby incorporated by reference in its entirety.
  • meltblown web refers to a nonwoven web formed by extruding a molten thermoplastic material through a plurality of fine, usually circular, die capillaries as molten threads or filaments into converging high velocity, usually hot, gas (e.g. air) streams which attenuate the filaments of molten thermoplastic material to reduce their diameter, which may be to microfiber diameter. Thereafter, the meltblown fibers are carried by the high velocity gas stream and are deposited on a collecting surface to form a web of randomly dispersed meltblown fibers.
  • gas e.g. air
  • Meltblown fibers are microfibers, which may be continuous or discontinuous, and are generally smaller than 10 microns in average diameter
  • the term “meltblown” is also intended to cover other processes in which a high velocity gas, (usually air) is used to aid in the formation of the filaments, such as melt spraying or centrifugal spinning.
  • Another suitable bonding method is pattern bonding, wherein heated calender rolls or ultrasonic bonding equipment are used to bond the fibers together, usually in a localized bond pattern, though the web can be bonded across its entire surface if so desired.
  • Another suitable and well-known bonding method, particularly when using bicomponent staple fibers, is through-air bonding.
  • multicomponent fibers refers to fibers or filaments which have been formed from at least two polymers extruded from separate extruders but spun together to form one fiber.
  • Multicomponent fibers are also sometimes referred to as “conjugate” or “bicomponent” fibers or filaments.
  • conjugate fibers may be prepared from the same polymer, if the polymer in each component is different from one another in some physical property, such as, for example, melting point or the softening point.
  • the biodegradable polymeric substrate of the present invention is prepared from a biodegradable polymer which is hydrophobic or has a low degree of wettablility. It is desirable to render the biodegradable polymeric substrate hydrophilic in many applications.
  • the biodegradable polymeric substrate may be a sheet-like material, such as a sheet of a film or a foamed material.
  • the sheet-like material also may be a fibrous web, such as a woven or nonwoven fabric or web.
  • the substrate also may include polymer fibers, per se, or polymer fibers which have been formed into a fibrous web.
  • the fibrous web desirably will be a nonwoven web, such as, but not limited to, a meltblown web, a spunbonded web, a bonded carded web, or an air-laid web.
  • the substrate also may be a laminate of two or more layers of a sheet-like material.
  • the biodegradable polymeric substrate may be rendered hydrophilic with a durable hydrophilic treatment by one of two methods.
  • the biodegradable polymeric substrate is rendered hydrophilic by subjecting the substrate to a corona glow discharge.
  • the biodegradable polymeric substrate having a surface is subjected to a corona glow discharge to render the surface hydrophilic.
  • such dose will be in a range of from about 15 to about 350 w-min/ft2 (from about 10 to about 226 kJ/m2). Most desirably, dose will be in a range of from about 20 to about 80 w-min/ft2 (from about 13 to about 52 kJ/m2).
  • the corona glow discharge treatment is applied to the substrate under ambient temperature and pressure; however, higher or lower temperature and pressures may be used.
  • modified polysaccharides include modified celluloses or cellulose derivatives, such as hydroxyethyl cellulose, hydroxypropyl cellulose, methyl cellulose, ethyl cellulose, methyl hydroxypropyl cellulose, ethyl hydroxyethyl cellulose, and carboxymethyl cellulose; starch and pectin derivatives, such as carboxymethyl starch, starch aldehyde, and pectates; and animal product derivatives, such as carboxymethyl chitin and carboxymethyl chitosan.
  • modified celluloses or cellulose derivatives such as hydroxyethyl cellulose, hydroxypropyl cellulose, methyl cellulose, ethyl cellulose, methyl hydroxypropyl cellulose, ethyl hydroxyethyl cellulose, and carboxymethyl cellulose
  • starch and pectin derivatives such as carboxymethyl starch, starch aldehyde, and pectates
  • animal product derivatives such as carboxymethyl
  • the coating does not significantly depress the surface tension of an aqueous medium with which the coated substrate may come in contact.
  • the surface tension depression of such an aqueous medium may be less than about 10 percent.
  • the coating may first be applied to the substrate and then the substrate may be subjected to a reactive species field.
  • the strength of the field of reactive species may be varied in a controlled manner across at least one dimension of the fibrous web.
  • the extent or degree of hydrophilicity of the coating is directly proportional to the strength of the field.
  • the hydrophilicity of the coating of polymeric material will vary in a controlled manner across at least one dimension of the fibrous web.
  • the add-on amount of the hydrophilic polymer in the coating applied to the substrate is generally in the range of about 0.01 wt % to about 2.0 wt %, and desirably between 0.05 wt % and 1.0 wt %, most desirably between about 0.1 wt % and about 0.5 wt %, each based on the dry weight of the substrate and hydrophilic polymer in the coating.
  • the effectiveness and durability of the treatments in making the fabric hydrophilic was tested using the inclined run-off test.
  • rectangular strips of the spunbond fabric were cut to the dimensions of 16 inches long and 4.5 inches wide.
  • the web was placed on an absorbent material of identical dimensions composed of 58% wood pulp (CR 1654 available from Bowater Inc., Coosa Pines, Ala.) and 42% superabsorbent (Favor SXM 880 available from Stockhausen Inc., Greensboro, N.C.) densified to 0.2 grams/cc with average basis weight of about 800 grams per square meter.
  • the spunbond fabric was placed in contact with the absorbent on a 30 degree inclined plastic sheet.
